This study aims to identify saponin compounds and test the antioxidant activity contained in the leaf extract of Thalassia hemprichii seagrass from Tomini Bay Coastal Waters. Seagrass contains various bioactive compounds, one of which functions as an antioxidant, and is rich in protein, fat, fiber and minerals. This research consisted of extraction, saponin test, and antioxidant activity tested using 2,2-diphenyl-1- picrylhydrazyl (DPPH). Thalassia hemprichii methanol extract has saponin compounds, ethyl acetate extract is not detected to have saponin compounds. Saponin content of methanol extract using the gravimetric method was 12.63%. The antioxidant activity value of IC50 T. hemprichii is 1.25 ppm or 1.25 mg/L.
